Value Collection SC00186247 MT2 to MT4 Morse Taper Adapter

Product Description

The VALUE COLLECTION SC00186247 is a Morse taper extension adapter designed to connect machine tool spindles and accessories with mismatched taper sizes. It accepts an MT2 inside taper and presents an MT4 outside taper, allowing a smaller-shank tool to seat in a larger-bore spindle or tailstock. The body is medium carbon steel with a soft construction and a hardened tang for durability at the drive point. Overall length is 8.5 inches. This adapter is installed by machinists and tool-room technicians on lathes, drill presses, and milling machines where taper extension or conversion is required.

This adapter is suited for machine shops, maintenance facilities, and job-site operations that run MT2-shank tooling in MT4 spindles or tailstocks. Typical applications include drill chuck mounting, reamer holding, and live or dead center extension on manual lathes. The 8.5-inch OAL adds reach between the spindle and the tool, which is useful when workpiece geometry or fixture depth demands additional clearance.

Key Features

• MT2 inside taper accepts standard MT2-shank tooling
• MT4 outside taper seats directly into MT4 spindles and tailstocks
• 8.5-inch overall length provides extended reach for deep-bore or fixture applications
• Medium carbon steel body balances toughness with machinability
• Hardened tang resists deformation during tool ejection
• Soft body allows field grinding or re-taper if required

Compatibility

Designed as a standard extension adapter for machine tool spindles and tailstocks with an MT4 receiving bore and MT2-shank tooling, including drill chucks, centers, reamers, and similar accessories.

Installation Notes

Installation is performed by a machinist or tool-room technician. Power down and lock out the machine before inserting or removing any taper adapter. Clean all taper surfaces of oil, chips, and debris before seating to ensure full contact and prevent fretting. Use a drift punch and the machine drift slot to eject the adapter — never strike the spindle or quill housing directly.
